Crimeware authors unleash bird flu-themed Trojan

Today brings further proof that no human disaster these days arises without been exploited by internet ne'er-do-wells. Hot on the heels of a spam campaign punting Tamiflu, the drug believed most effective at protecting humans from the potentially-lethal H5N1 strain of the bird flu virus, comes a piece of malware designed to tap into topical concerns about the disease.

The Naiva-A Trojan masquerades as a Word document containing information about the bird flu epidemic in order to dupe unwitting Windows users into opening the maliciously constructed file. Once executed, the malware uses two Word macros to run and install a second item of malicious code, Ranky-FY, onto infected PCs. Ranky-FY gives hackers the ability to control compromised PCs.
